Developer frustrations with iCloud Core Data syncing have been much in the news of late, but for those who are wondering — at a technical level — what the fuss is all about, Rich Siegel of Bare Bones Software lays out what is involved with iCloud data syncing, and where developers are experiencing problems.

The Next Web’s Emil Protalinski explains the amusingly awful bug in OS X 10.8 Mountain Lion that causes most Mac apps to crash when you type the string file:/// (you have to capitalize one of the letters in the word “file,” which we didn’t to avoid inadvertent crashes). The bug turns out to be in Apple’s Data Detectors code, and affects only apps that use NSTextFields. So the Finder, Safari, Messages, and TextEdit all crash, as does the Mac’s error reporter, but BBEdit and Firefox do not.

3D designer and illustrator Peter Zigich has posted a number of beautifully rendered mockups of what a future Mac Pro could look like, were it to use significantly more efficient CPUs. It is, of course, highly likely that Peter’s designs will bear no resemblance to what Apple is reportedly planning for this year’s Mac Pro refresh, but it’s still fun to ponder whether or not his designs could work.
